Pulseling — Muscles & Movement Muscle Machine Yard
Hi!
I'm Pulseling.
Welcome to Muscle Machine Yard!
Will you help me investigate muscles & movement?
The Grumblies have mixed up our clues.
Let's check the evidence!
Muscles can contract, becoming shorter and pulling on structures.
Muscles work with bones and joints to produce many movements.
How do contracting muscles act in this model?
- A. By becoming liquid
- B. By pulling
- C. By turning into bone
The answer is B: By pulling
Muscles can contract, becoming shorter and pulling on structures.
Muscles work with bones and joints to produce many movements.
That clue helps us make sense of this place.
Muscles often work in groups with opposing actions.
One pulling model alone does not show all the coordination
in a real arm.
Why use two opposing cords?
- A. To model different pulling actions
- B. To show one cord pushes from both ends
- C. To show cords become nerves
The answer is A: To model different pulling actions
Muscles often work in groups with opposing actions.
One pulling model alone does not show all the coordination
in a real arm.
Hmm...
how does that connect to our first clue?
Our model has two cords on opposite sides of a hinged arm.
Pulling one bends the hinge in one direction;
pulling the other changes its position back.
What allows the arm pieces to bend?
- A. A rigid bone melting
- B. A painted line without a joint
- C. The hinge representing a joint
The answer is C: The hinge representing a joint
Muscles can contract, becoming shorter and pulling on structures.
Muscles work with bones and joints to produce many movements.
